MACHINE FOR MAKING PAPER PAILS.

SPECIFICATION forming part of Letters Patent No. 341,163, dated May 4,1886.

Application filed February 8,1886. Serial No.191,217. (No model.)

To all whom it 11mg concern:

Be it known that I, FRANKLIN D. PEOK, a citizen of the United States,residing at Elkhart, in the county of Elkhart and State of Indiana, haveinvented new and useful Improvements in Machines for Making Paper Pails,of which the following is a specification, reference being had to theaccompanying drawin s.

%\Iy invention relates to improvements in machines for making paperpails; and it consists of the peculiar and novel construction andcombination of parts, substantially as hereinafter fully set forth, andspecifically pointed out in the claims.

The objects of my invention are to provide improved means for conveyingthe pulp from a receptacle to the proper forms on which the pails arefirst made, and which at the same time shall permit of the properdischarge of surplus water or other fluid that is forced from the pulp;to provide improved means for conveying the pulp from the receptacle toa traveling carrier; to provide forms of the proper configuration thatare readily and quickly removable, to be replaced by other forms ofsimilar construction; to provide means for exerting the proper requisitepressure on the forms to compress the pulp very firmly and compactly,and at the same time force any surplus water or other fiuid from thepulp; to

provide means that shall be conveniently operated to release thepressure-rolls from bearing and pressing on the forms when the latterare to be removed; to provide means for positively rotating thepressure-rolls; to provide troughsfor conveying and discharging the wa-V ter or other fluid pressed from the pulp by the pressure-rollers, andto provide means that are simple and strong in construction and thor---oughly effective and reliable in operation.

I attain the above-named objects by the mechanisms which are illustratedin the accompa nying drawings, in which Figure l is a side elevation ofa machine for making paper pails,constructed in accordance with myinvention. Fig. 2 is a horizontal sectional view on the line :0 w ofFig. 1. Fig. 3 is a transverse vertical sectional view on the line 3 yof Fig. 2. Fig. 4 is alongitudinal sectional view on the line zz of Fig.2. Fig. 5 is a detail view of one of the removable forms with itsstandard and frame, and Fig. 6 is a similar view of the pressure-rollerand the means for elevating and depressing the same.

Referring to the drawings, in which like letters of reference indicatecorresponding parts in the several figures, A designates supportinguprights or columns that are suitably disposed and arranged to support acover or roof, a, to protect my improved machine and provide forsuspending or holding hangers of the pressurerollers, as will more fullyappear presently.

B designates a receptacle or vessel, of any preferred form anddimensions, to receive the pulp from which the pails are to be formed,the pulp being made before it is deposited in the receptacle.

0 designates a roller that is arranged to revolve in the pulp-receptacleB and convey the pulp therefrom to a traveling carrier, D, that rotatesin a horizontal plane around a rotatable center and supplies the forms Ewith pulp from the receptacle B. This conveying-roller 7 5 G is rigidlymounted on a shaft, 0, that is journaled in proper bearings on thereceptacle B. One end of this shaft 0 is extended beyond the receptacleB, and receives a pulley, crank, or other suitable mechanical device forrotating the shaft from a motor or other source of power, and the otherend of this shaft, which, for convenience, I will term thedriving-shaft, carries a spur gear-wheel, c, that meshes with a rack, d,on the traveling carrier D.

The traveling carrier D is made circular in form,and it comprises aninner and outer ring, d d to which are secured the edges of anintermediate canvas or other fabric section, (P, that is stretched andheld taut on the rings or 91: open frame. The inner ring,d',is providedon its under and upper surface with teeth or cogs, that constitute theracks d,and said inner ring of the carrier has radial arms (1*, whichmeet at a common center and are rigidly secured 95 or keyed upon avertically-disposed shaft, (2 which isjournaled at its ends in bearingsD D". The bearing D is rigidly held in place on the floor, ground, 810.,and the bearing D is formed in or rigidly affixed toa cross-beam, 10o D,that is supported at its ends on columns or uprights D. In lieu ofsupporting the shaft d in the beam D, the latter and its columns may bedispensed with and the upper end of the shaft (1 journaled in a properbearing properly affixed to the cover or roof a. The traveling carrier Dis thus composed of an open-geared frame and fabric section, and thecarrier is disposed in an approximately horizontal position, so that oneedge thereof shall be lower than the other edge that lies diametricallyopposite therefrom, or the carrier may be said to occupy ahorizontally-inclined position and to rotate ina horizontal plane.

The conveying-roller G bears against the lower under face of the canvasor fabric section of the open frame of the traveling carrier, and thepulp from said conveying-roller adheres to the canvas or fabric of thetraveling carrier until it comes in contact with the periphery of theforms E, to which it adheres to form the body of a pail. These forms Eare shaped to correspond to the curvature or inclination of the vesselor pail body which is to be formed thereon,and in thepresent instance Ihave shown said forms E in the shape of a frustum of a cone with theirsmaller diameters on the inner end or nearest the center of therotatable traveling carrier D. The incli nation or angle of the carrierD corresponds to the inclination of the forms E, so that the peripheriesof the latter can bear equally at all points against the fabric sectionof the carrier to distribute the pulp evenly and uniformly on the forms,and the conveying-roller Ois also made frustumshaped, to uniformly applythe pulp to the fabric of the traveling carrier D.

In the drawings I have shown two forms E; but it will be understood thatthree or more may be employed if it is deemed desirable.

Where onlytwo forms are provided for the machine they are used one at atimethat is to say, when the form of standard No. l is in use orreceiving pulp from the carrier, the form of standard No. 2 is removedor out of contact with the carrier, and vice Versa, as it will bereadily seen that if both are allowed to remain in use the form ofstandard No. 1 will take up all ornearly all of the pulp from thecarrier, and the form of standard No. 2 will receive a very meager or nosup ply at all. Ihave also provided and arranged means whereby bothforms can be allowed to remain in their standards and to bring or adaptthe carrier to supply either one of the forms with pulp, which devicesand their operation will be presently described.

The rollers or forms E and their standards are disposed beneath theelevated or higher end of the horizontallyrotatable carrier, and thecarrier is normally elevated above and out of contact with theperipheries of the forms. Each form is provided at its ends or headswith pins or studs 6, which are loosely mounted in proper bearings, f,which are secured to or cast with a frame, F, that is arranged to slidevertically in grooves or recesses g of standards G, which are connectedat their lower ends. These vertically-sliding frames F and their fixedstandards G are of any suitable form or construction, and the forms Eare loosely mounted in the bearings of the frame, to adapt them to bereadily detached or removed and interchanged, after they have beensupplied with pulp, with forms of similar construction that are to befilled with pulp. The sliding frames are adapted to be elevated to anysuitaable height to bring the forms into proper juxtaposition to andcontact with the fabric section of the carrier D, and when the frame andform have been properly elevated and adjusted they are rigidly held inplace by means of a catch, h, that enters a notch or socket in theframe, or by any other suitable or preferable means. The frustnm-shapedforms are rotated by frictional contact with the periphcry of a rotatingpressure-roller that bears on the canvas section of the carrier, and itwill be readily seen that when the carrier is'in motion it will applythe pulp to the form,and at the same time the form will be rotated bythe rotatory pressure-roller, which evenly and uniformly applies thepulp to all parts of the form throughout its entire periphery. After theform has been covered or coated with the pulp to the required thicknessit islowered and re moved from the frame, without stopping or otherwiseinterfering with the motion of the machine, and its place supplied byanother form of similar construction.

Each form is acted upon by a pressure-roller, I, that is suspended abovethe fabric section of the traveling carrier and serves to compress thepulp very firmly and compactly on the form. The pressure rollers aremade frustum-shaped to correspond with the angle of the form and theinclined rotatable carrier D, and the conveyingroller 0 also has apressure roller, I, bearing thereon with sufficient force to cause thepulp from the conveying-roller to adhere to the carrier D; but the forcewhich the roller I exerts on therollcr O isregulated so that it isconsiderably less than the pressure of the rollers I on the forms E.

The rollers I and I are each provided at their ends with studs or pins2', which are free to move in slotsj, that are formed invertically-disposed arms j of hangers J, which are suspended from thecover or roof a. The hangers may be of any suitable construction, andthe lower ends of the slotsj may be left open and carry a removable pin.j, whereby the pressurerollers can be readily removed.

I will now proceed to describe my preferred form of device forregulating the pressure on the pulp and form.

A yoke, K, is connected loosely to the studs 03 of each of the rollers,to permit them to turn freely, and to a lug, 7c, of this yokeis pivoteda lever, L, which extends through and is pivotally supported within aslotted portion,

Z, of one of the armsj of the hanger J. Asimilar lever, M, is pivoted ator near its middle to a suspended rod, m, and one end of this lever ispivoted to the free end of the lever L, and to the opposite end of thelever M is pivoted a link, N, which connects with an operating han- IIOd1e-lever, O, which is pivoted at one end to a standard, 0, and has atooth, 0, adapted to engage and be retained by one of aseries of teethon a rack'bar or standard, 0. This handle-lever O is normally held downby a coiled spring, 0, or by a weight, so that the pressure of thepressureroller can be varied. It will be seen that when the free end ofthe spring-actuated pivoted handlelever is elevated the connected endsof the pivoted levers L M will be depressed and the inner end of thelever L will be elevated, to raise the bracket or yoke K and thepresslire-roller, and when the free end of the handle-lever is depressedthe pressure-roller will be lowered, to bear against the travelingcarrier, the degree of elevation or depression depending upon the amountof movement of the handle-lever, as will be readily understood.

Each of the pressure-rollers I is positively rotated by motiontransmitted thereto from rotatable traveling carrier D, through apinion. P, rigidly secured to the extended inner stud of thepressure-rollers I, and meshing with the teeth or cogs of the rack-baron the upper surface of the rotatable carrier.

Q designates troughs,that are arranged parallel with the pressurerollersI and trans versely across the traveling carrier, and this trough issuspended abovethe traveling carrier by means of rods or cords q. Thetroughs are to receive and discharge the water or other fluid that isforced from the pulp through the porous fabric or canvas of thetraveling carrier by the pressure-rollers and to convey the same awayfrom the forms, to prevent the pulp thereon from becomingtoo wet, andthus they can be more quickly dried.

When the forms E are elevated to bring them into operation, they bearagainst and elevate a portion of the flexible fabric of the travelingcarrier, so that the fabric is inclined for a portion of its length, andas the pressurev'roller forces the surplus water from the carrier andthe form.

pulp the water will permeate through the fabric and descend the inclinedportion of the fabric, and flow into the discharge trough or spout, bywhich it is conveyed from the The inclined discharge spout is suspendedabove the t-ravefing carrier, and its open side is arranged to bear onthe fabric of the carrier, whereby, when the lat ter is elevated by theform to produce the incline, the water from the pulp will readily enterthe trough.

Each of the troughs is provided with an inclosing-wall around itsseveral edges, except at the part or side that lies alongside of thepressure-roller, which is left open, so that the water, 830., can passinto and through the trough, and one end of the trough or dischargespoutis contracted and extended beyond the edges of the carrier, to conveythe water therefrom and discharge it into proper receptacles, thetroughs being arranged in an inclined position, to more efi'ectuallydischarge the water.

Q designates a similar discharge-spout for the pressure-roller I, thatis suspended and disposed in an inclined position, one end thereof beingleft open to receive the water that is forced through the fabric sectionof the carrier by the rollers O and I.

The operation of my invention is as follows: 'I he pulp, which hasalready been prepared, is poured or otherwise discharged into thereceptacle or hopper B and the pressure-roller I adjusted to bear on theconveying roller 0 to the proper degree, the force thereof beingregulated, so as to only press a portion of theewater from the pulp andto cause the pulp to adhere to the carrier. One of the forms E isadjusted or elevated to bear against the fabric section of the carrier,and the pressure-roller I lowered to bear on said canvas section of thecarrier above the latter and the form, after which power 011110 tion iscommunicated to the drivingshaft c. The roller 0 is thus revolved toconvey pulp from the reservoir or reoeptacleB to the traveling carrier,which conveys it to the form E, where it is discharged onto the latter.Simultaneously with the rotation of the conveying-roller O thehorizontally-rotatable traveling carrier D is revolved, and the motionthereof is transmitted to the form E and pressureroller I by frictionalcontact between the form and pressure-roller and the gearing dB. Thepositivelyrotatcd pressure-roller serves to rotate the form by hearingthereon, and to press the surplus water from the pulp through thecanvas, and it then, passes into the dischargespout or trough Q, and atthe same time the pressure-roller compresses the pulp compactly andfirmly on the form E. \Vhen the form E is coated with pulp toasufficientthickness, the pressure-roller I that bears thereon is elevated byelevating the handle-lever O and the sliding frame F lowered, afterwhich the form with the pail thereon is removed and its place suppliedwith another form of similar construction. Simultaneously with theelevation of one pressure-roller and the de pression of the form thatcoacts therewith another pressure roller and form are adjusted for use,and this operation is continued without requiring the stopping of themachine.

It will be observed from the foregoing description, taken in connectionwith the drawings, that I provide a machine which compresses the pulpvery firmly and compactly on the form of required shape, and that the vlatter is readily interchangeable withoutstopping the motion of themachine. I provide for the proper supply of the pulp and the dischargeof surplus water, and also regulate the pressure on the forms, so that agreater or less quantity of pulp can accumulate thereon, while at thesame time the pulp is evenly and uniformly applied throughout all pointson the periphery of the form.

I do not desire to limit myself to the details of construction and formand proportion of parts herein shown and described as an embodiment ofmy invention, as I am aware that many changes may be made withoutdeparting from the principle thereof.

I am aware that it is not broadly new to employ a horizontal rotatablecarrier having a sieve, a forming-roller bearing on the upper surface ofthe carrier and mounted in a vertically-movable frame fitted in properstandards,

and a pressure-roller on the under side of the carrier beneath theforming-roller and having a rack which meshes with a pinion on ahandshaft to adjust the pressure-roller vertically.

I am also aware that it is not new to employ a centrally-supportedhorizontal felt-carrier which rotates about its'axis and is inclined,atrough in which works a conveying-roller to transfer thepulp to thefelt-carrier, apressureroller to the conveying-roller, a supplementalframe pivoted centrally to the main frame and carrying a forming rollerat each end, the frame being rotatable on its shaft to bring eitherroller in contact with the felt-carrier, a pressure-roller to theforming-roller, and a shaft having belts to rotate the pressure-rollers.
